I have an 01 330ci and it has just hit the 120k mark and have noticed the ride quality dip substantially. I'm looking to do an entire suspension refresh and wanted to know what you guys recommend should be replaced suspension wise on a high mileage daily driver. Thanks.

If you want to go for the gusto I'd look at doing the following; Lower control arms, Lower control arm bushings, Front stabilizer links, Front tie rods, Front strut mounts, Rear subframe bushings and hardware, Rear differential bushings and hardware, Subframe bushings and hardware, Lower wishbone bushings and hardware, Upper wishbone bushings and hardware, Control arm front bushings and hardware, Rear strut mounts, Z3 reinforcement plate, Rear stabilizing links, and of course new Hardware. If the shocks are originals there is a chance they are also worn and I'd look at replacing them as well.

Thanks. I'll definitely have to look into these items. Wish there was a package of all these items together to bypass the headache.

Well, I do have packages which do exactly that. HERE is a link to them for the E46 330ci. We have a couple different levels repair with a few different brand options. If you have any questions about them feel free to shoot me a PM!

I recommend going with a site sponsor like ECS Tuning or Turner Motorsport. They have a lot of good pre-assembled packaged that have all the stuff you need for a suspension refresh.

Yes, you can, but if you do it will raise the front of the car and lower the rear slightly because the M3 has a heavier front end. It doesn't look very nice, and the ride will be bouncy with your stock dampers because they will be valved for softer springs and will likely be worn out as well.

oh, i thought they will be stiffer not bouncier. did not think about the front end could raise. i guess i should stick to changing the shocks!
